Abstract The form of the discharge during its evolution on the pollution is important for two essential reasons: firstly to better know the physical mechanism of the evolution of the discharge, and secondly to verify the validity of the mathematical equations used to interpret the phenomenon of flashover. in the existing literature, the discharge propagates in a tubular form, its circular foot displaces or slips on the pollution. The mathematical equations modeling the system have been based on this tubular aspect. To verify the validity of this form, we measured the current during the evolution of the discharge in two experimental models. From the graphical analysis of the measured current I(t), we deduced that the discharge doesn't evolve in a tubular form but takes the aspect of a foot that lies down. Then the theoretical dynamic features calculated using the tubular dynamic aspect is only the sum of static independent points distinctly different from the experimental characteristic.
